Sitting member Natasha Griggs will again contest the Lower House seat of Solomon in this year's federal election after winning party endorsement.
The Country Liberal Party (CLP) on Saturday voted to preselect Ms Griggs for the seat, which covers Darwin and the nearby city of Palmerston.
It had been expected the preselection contest would be tough, with Darwin doctor Peter Bourke up against Ms Griggs.
"I am absolutely delighted," Ms Griggs said from Tennant Creek where the CLP Central Council met to vote on the candidates.
"I am ready to once again take the fight to Labor for the people of the Territory," she said.
Following the announcement of her victory Ms Griggs spoke with Dr Bourke.
"He said he would support me and while he was disappointed he understands the party processes," she said.
Senator Nigel Scullion was again endorsed for the number one spot on the CLP's ticket for the Northern Territory, with Linda Fazldeen winning the second spot.
The CLP's Central Council meeting will wrap up on Sunday, with some in the party privately speculating a vote of no-confidence will be held in NT Chief Minister Terry Mills.
Mr Mills has angered some in the party because of recent decisions to raise electricity prices in the NT by 30 per cent.
After a big swing against the CLP in a recent by-election NT Attorney-General John Elferink began counting numbers for a possible leadership challenge to Mr Mills.
The challenge never eventuated and Mr Elferink offered his resignation, but Mr Mills allowed him to retain his portfolio.
